+### Traits
+
+```mist
+pub trait Drawable {
+    void draw(&self);
+}
+
+pub trait Comparable<T> : Eq {
+    i32 cmp(&self, T other);
+}
+```
+
+Trait requirements are specified after `:`:
+
+```mist
+trait MyTrait : SuperTrait + OtherTrait {
+    void required_method(&self);
+    void another(&self);
+}
+```
+
+### Impl Blocks
+
+```mist
+impl MyType {
+    void method(&self) { }
+}
+
+impl Trait for MyType {
+    void method(&self) { }
+}
+
+impl<T> GenericTrait<T> for MyType {
+    void method(&self, T value) { }
+}
+```
